STEEN ErAL METHOD AND MACHINE Foa BAG MAKING .MSGMESQ, MMQSQ No Filed June 11. 1951 @NNN United States Patent O METHOD`AND MACHINE FOR BAG MAKING Harford K. Steen, Newburgh, N. Y., andHarold L. Thompson, deceased, late of Newburgh, N. Y., by Thelma V.Thompson, administratrx, Newburgh, N. Y., assignors to Interstate BagCompany, Walden, N. Y., a corporation of New York Application June 11,1951, Serial No. 230,906 11 claims. (Cres-s) The present inventionrelates to a method and machine for bag making. While the invention isparticularly applicable to making handled bags for carrying merchandiseof various types, it is also of general application in the bag-makingart. Starting with a continuous web of paper or other bag makingmaterial, it has been customary to form a tube and thereafter cut thesame into bag lengths and bottoming the same. Sometimes the web is rstsevered and the tube then formed from the severed length. Such methods,however, though quite standard in the art, have certain drawbacks.Foremost is the problem incident to the formation of the bottom of thebag. It will be noted that if the bag tube were to be transverselysevered by a simple out making both bag sides the same length,difficulty would be had when one end of the tube was turned over to formthe bottom since the outer layer would not be in contact with thereverse side of the bag against which it is to be pasted. Therefore itis the practice so to cut the bag tube as to make one side longer thanthe other. While this enables the bottom to be formed satisfactorily,the increased length of one side of the bag is had at the expense of thecorresponding side of the bag `next following whereby one top edge isbelow the other.

However, the capacity of such a bag is determined by the shortest lengthof the shorter side. Even though advantage is taken of this fact tofacilitate the opening of the bag, yet the bag opening can befacilitated in other ways (as by making use of the handle) whereby theincreased length of one side represents in the aggregate a tremendousloss of paper or other material constituting the bag. In some instances,when the bag has thus been formed, the excess material at the top of thebag is cut off in order to present even,.square edges for the two bagsides.

It is thus a principal object of the invention to provide a continuousmethod and machine for bag making in which two sides of the bag areformed from separate webs which are severed to form preferably straighttop and bottom edges but of different lengths so that the longer lengthmay contribute in part at least the necessary bottoming material.

It is a further object to provide a continuous method and machine forbag making to produce a bag with handles which may be secured to the bagat the inside surfaces thereof. When handles are applied to a bag thathas already been tubed, there is no easy Way to secure the ends of thehandle to the inside surfaces of the bag, hence they are commonly placedon the outside. This, however, is a drawback for the reason that handlessecured Vto the outside of the bag, especially by being pasted thereto,are much more easily peeled olf as when the loaded bag, for example, isgrasped by the handle at one side thereof.

When, however, the handles are pasted on the inside surfice A stillfurther object -is to form a gusset in one of the webs during its feedinto the machine, thereby produc= ing a gusseted bag.

A still further object is to provide improved bottoming mechanism as apart of a unitary bag making machine.

A further advantage of the improved method and machine is that the iirstbag side, for example, may be made of a different material from thesecond bag side. For example, it may be made of a transparent materialsuch as cellophane or it may be made of a higher grade of paper whichwill enable a better printing job to be done upon it than would be thecase with the second bag side.

Still further objects and advantages of the invention will becomeapparent as the following description proceeds, taken in connection withthe accompanying drawings in which Fig. l is a View in longitudinalvertical section, partly diagrammatic, of the improved machine forcarrying out the operations of bag making in accordance with theimproved method, save only for the operations of forming bag handles andfor forming the gussets in one of the webs shown in Figs. l-A and l-Brespectively;

The invention is exemplified in the manufacture of a handled bag shownin the lower right hand corner of Fig. 5 of the gusseted type, havingwhat is termed a square bottom. Herein the essential steps of the methodare illustrated of advancing a first Sheet lil which has been severedfrom a web 11, stamped with a band of adhesive 12 in the form of a Uaround the periphery of the sheet except for the top edge thereof, andalso a glue spot 13 for the securement of the handle 14. Si multaneouslya second continuous sheet 1S is advanced, from a supply not shown inFig. 5, said sheet being; formed (it a gusseted bag is beingmanufactured) with, gussets 16 and a glue spot 17. Next, the handle lahas the adjacent end thereof secured to the rst sheet or bag side 10 bybringing such end tightly against the glue spot 13, then the compositeso formed is superimposed on gusseted sheet 15 which is shorter than thesheet 1t, thereby permitting the bottom end 18 to be folded over andcaused to adhere to the outer surface 0f the second sheet 15, therebyforming the bottom of the bag. In the act of superimposing the two bagsides, the unattached handle end is secured to the .second sheet 15 aswill be apparent from an inspection of this figure (Fig. 5). As part ofthe handle forming method, a transverse crea-se or fold line 19 isformed in each leg of handle 14 at an angle preferably 45 degrees to thehandle axis in order that the handle may, when the bag is opened, befolded so as to line the inside half periphery and maintain it in openposition as.- disclosed.

in pending application of `Steen-and` Thompson, tiled JulyA 8 1950,Serial No. 172,736, `now Patent 2,652,187, of which this application isa continuation in part.

Reference to Figs. l, l-A and l-B will indicate how the ,stepsillustrated in Fig. are carried out on the improved machine; First',however, it will be convenient to describe the mechanism of Figs. lA andl-B for forming the handle material and the` gusseted web respectively.In Fig. 1A, bag handle material 25 from a bulk supply roll 26 is fedthrough tensioning rolls 26, 27, 28 to a folding device (station A)consisting of a former 3@ which, with the assistance of ting-gers 32which initiate the side folds, folds the bag handle material or tapeover upon itself to increase the strength thereof, being aided by thedraw rolls 33, 34 to the right of former and guided by roll 35 to theleft thereof.

The manner of forming the paper strip to forni the handle material issubject to considerable variation to make a reinforced handle material.In the embodiment shown the material is folded to form a strip having across section shaped substantially as a flattened C (shown best in Fig.5). Various other means of forming the handle are described in thecopending application of Steen, Serial No. 234,320, filed June 29, 1951.The handle material having been formed, it is severed into strips of thedesired length by means of cutoff roller having knife 41 and cooperatingwith backing roller 42. Rollers33 and 34 feed the strip between therollers 40, 42 (which are positioned to permit this), after which thestrip is cut off by the action of the blade 41 carried by the roll 49.The severed strip is then seized by the pinch rolls 43, 24 (the latterhaving the relieved portion 46) and fed to the drums 85, 86 for furtheroperations to be described. The rate of feed of the `strip between rolls40, 42 prior to severance by blade 41 is dependent upon the length ofhandle desired and is governed by the number of revolutions of feedrolls 33 and 34 per cycle.

In Fig. lB the second sheet 15 is fed from a bulk supply, not shown,through a gusset former (station B) consisting of brackets 50 only oneof which is shown) upon which is secured a cross bar 52 carryingsupporting members 53 for former plates 54, 5S, which are also seen incross section Fig. 2. As will be evident from Fig. 1-B, the plates 56,57 which are attachedto blocks 5S, 59 respectively cooperate with theplates 54 and 55 to form a progressively narrowing throat by means ofwhich the sheet 15 has gradually formed therein the gussets 16. Also, atthe time when the fol. ing of the sheet commences, folders are providedwhich operate to turn the edge of the sheet to make a further 180 degreefold to create parallel strips 63 serving to unite the gusseted sheet 15to the sheet 10 by means of the glue deposit 12. Spring pressed rollers64, 65 assist in creasing this fold last mentioned. A gusset having beenformed in either edge of the web 15, a glue spot 17 is printed thereuponby means of the glue applicator rolls generally indicated at 66 anddriven from the mainv drive shaft 10ft-S by a sprocket chain 15h-A, andgiven a final creasing by means of the rollers 67, 67' which also serveas draw rolls for feeding the web, together with draw rollsS, 6B of Fig.l.

Reference may now be had to Fig. 1 which shows the feed of the top sheetweb 10 through a printer 69 (if this is to be used for printing eitherwords or decoration as may be desired), thence between feed rolls 70, 71to the cutting roll pair 72, 73 which sever the web into sheetsconstituting the first or top bag sides which are now fed by feed rolls74, 75 (one of which 74 is a segmental roll to enable the severed sheetto be speeded up) to glue applicator roll 76 which prints a gluecontiguration designated 12 and simultaneously prints the glue spot 13of Fig. 5, the sheet being held against the roll 76 by the main drum 77.

The rst sheet which has' now been severed from the web contains whateverprinted matter' it is' desired to have on it and has had the glueconfiguration also printed upon it, whereupon it is secured to the drum77 by the combined action of clamps 78 and pins 79 (each preferably twoin number of which only one each is seen in Fig. l). The pins, after theclamping action to be described has taken place, are caused to piercethe sheet, being actuated by cam track 80, pivoted cam follower 81,pivotally attached to pin 79, the cam follower 81 being caused to followthe track $0 by means of spring d2. In this arrangement each of the pins79 is thus positively actuated to pierce the sheet and is retracted bymeans of the spring 82. Clamps '78 may each be in the form `of a bellcrank pivoted at 83 and terminating in cam follower roller 83', thelatter is caused to follow cam track 84 by means of spring 84. The sheet10 is thus held securely on the drum and in such position is brought tothe point where it is ready to receive the handle 14 which has been cutand conveyed by means of mechanism now to be described. v

By means of the segmental roll 44 and the cooperating roll 43, Fig; l,the cut handle strip has been fed l'between a second drum S5 and a thirddrum 86 provided with suitable handle folding elements. Thus shortlyafter the handle strip is received between the drums 85 and 86, it isgripped by means of a pin 87 on drum 86, pin 87 serving to cause thehandle end to follow the drum 86. After this occurs a tucker -blade S9on drum 86 creates an inciplient fold in the handle strip by pushing itinto recess 90 of the lower drum 85. When this occurs a pincer blade 81operates to grip the fold within the recess 90 due to the action of cam92 acting upon pivoted cam follower 93 attached to blade 91 and spring95. Thereby the folded handle is securely held by the drum 85, continuedrotation of the drum 85 serving to pull the handle end form the drum S6to which it was momentarily attached by pin 87 which, as shown in Fig. lis spring-actuated to Withdraw it before the handle is gripped in thedrum S5 (cam 96 and spring pressed follower 97). Continued rotation ofdrum 85 brings the now folded handle against the surface of the maindrum 77 ahead of the formed end of sheet ltlupon which drum 77 thehandle is fixed by engagement with the xed pin 100, such pin passingthrough both legs or the handle. When this occurs the pincet blade 91will be caused to release the fold of the handle by the action of thecam 92 and the pressure between drums 77 and 85 will further cause theadjacent handle end to be stuck to the sheet 10 by contact with the gluespot 13. During the formation of the handle the score lines 19 areformed by means of a crease bar 101 in the roll 86 in cooperation with aresilient inset 102 in roll 85. Inl Fig. 5 a crease 19 in the right handleg of the handle has already been formed but the formation of the scoreline of the other leg of the handle has not yet taken place.

The assembly consisting of the sheet 10 and handle 14 (with the handlesecured against movement by engagement with pin 100) is now ready forengagement with the gusseted sheet 1S which has been prepared as abovepointed out in connection with Fig. 14B. Said sheet 1'5 now having been`severed by means of the cutting roll 103 acting against backing roll104, the same is fed by means of feed rolls 105, (105 being segmentalfor speeding up the travel of the cut sheet) to the bight between drum77 and` bottom former roll 107. Thereby the said sheets IG-and 15 aresuperimposed and the unattached handle leg is brought into contact withthe glue spot 17 on sheet 15 and the bag tube thus formed. In order,however, for superimposition to occur, the clamps 78 are momentarilyretracted by action of cam 84, the bag side 10 being kept from gettingout of position by means of the pins 79. After superimposition has beenhad, said cam? 84 operates to again-bring the clamps 78`int'o position'to` engage thev now completed bag tube. This back and forth movementofthe clamps 78 is had by the cam lobe 108 of cam 84. (See Figs. 1

and 3.) p

The further travel of the bag tube between drums 77 and roll 107 bringsinto operation the bottom forming mechanism comprised of pincer blade110 operating in a recess 111 and actuated by pivoted cam follower 112and cam 113. The elements are actuated to grip the fold in the bottom ofthe bag made by the tucker blade 11,4 `(Fig. l) in the roll 107. 'I'hebottom of the bag havingbeen thus gripped, the end of the sheet (10a) isnow folded against the outside of sheet by means of pivoted fingers 120having cam follower rollers 121 in contact with cam surface 122. t

Immediately prior to the action just described, a crease is formedacross the bag parallel to and spaced from thebottom of the unopened baga distance one-half the width of the expanded gusset of sheet 15 wherebyto facilitate the transverse folding of the expanded gussets against thebottom of the bag when the same is opened, such crease being formed by acreasing blade 123 in roll 107 which registers with a recess 124 in thedrum 77.

After this creasing action takes place, the pincer blade 110 is releasedenabling the bottom `of the bag to be released from therecess 111. Alsoit will be evident that the recess 125 of the roll 107 will enable thefingers 120 to extend beyond the periphery of the drum 77. Such recessalso enables the point at which the bottom folding takes place to bevaried somewhat depending on the size of the bag, for example. Furthertravel of the drum '77 subjects the completed bag to further pressingbetween drum 77 and drum 130. Means are provided at this point forstripping the completed bags from the drum- 77 in the form of a wedge orstripper 131 fitting into the bight between the drums 130 `and 77 andprojecting into aigroove in the latter together with endless tapes 132which pass around grooved guide rolls 133, 134 and are caused to comebetween the bags and the grooved drum 130. Outer tapes 135 are likewiseprovided which pass around pulleys 136 and 137,` a train of overlappingbags thus being conveyed from the drum 130 between the two tapes 132 and135. Reverting to drum 77, by the time the leading edge of the bag hasreached the stripper 131, the pins 79 and theclamps 78 are retracted bythe action of their respective springs so as to enable the strippingofthe bags to take place.

Reference to Fig. 1 will reveal the fact that in the embodiment shown,the main drum 77 is adapted to process three bags at the same timewhereas the roll 86 and the drum 85 are of such size and the arrangementis such that they are handling two handles per revolution of the drumS5. So long as the parts move in the i proper timed relation, thisarrangement may be varied by suitable gear change mechanisms (not shown)for varying the feed of the top sheet 10 and consequently its length.This change necessitates gear changes for the gussetsheet 15 and may ormay not require suitable gear changes for the handle feeding mechanismdepending on whether or not the handle length is to be changed. `Otheradjustments may be made as the need dictates as will occur to thoseskilled in the art.

It will be noted that the first sheet and the handle both are` pinned toor impaled upon said `drum whereby when they meet the second sheet theyare held securely against displacement in any direction. Also when thesecond sheet is superimposed upon the first, it too is pinned to thedrum whereby the three parts are efectively prevented frombeingdisplaced in the operation of bottoming the bag. It will further benoted that the clamps 78 act as stops for the advancing first and secandsheets.

` It is apparent that the various parts of the machine mustoperatestrictly in timed relation to one another. Toaccomplish `this thepartsare driven by gearing and chain drives as follows:

The main drive shaft 104-S upon which is secured the backing roll 104for the cutoff of the gusseted sheet 15 is geared to` drive shaft 10S-Supon which is mounted gear 156. In order to drive the feed rolls 67,67', 68, 68', the following is provided, viz: Idler gear 154 whichmeshes with gear 156 and gears 68'G, 68G, thus driving rolls 68', 68;train comprising gears 68G, idler 158, which meshes with gear 67'G andthat finally with gear 67G for driving rolls 67', 67. From drive shaft104-S sprocket chain 150-A drives the handle glue spot applicator roll(shown in the group 66).

In order to drive main drum 77 counter-clockwise the main shaft 104`S isgeared to idler 159 which in turn engages ring gear 77G. Idler 159 isalso geared to drive a roller 106 whose gear in turn meshes with gear105G. Gear 76G meshes `with gear 77G to drive the glue applicator 76.This in turn receives its glue from dauber rolls 163, 164, one of whichis immersed in the glue pot 165 (as shown in Fig. 4 dauber roll 163 isdriven by intermeshing gears 76G and 163G and 164 is not gear driven).

Gear 77G of drum 77 drives bottom former roll 107 by engagement withgear 107G. In order to feed the handle material through the machine, aseries of gears are driven by gear 77G which engages gear 85G of drum85. This in turn meshes with 86G secured on the shaft of the handlefolding roll 86. Herein the gear ratio is such that for each rotation ofthe drum two handles are delivered to drum 77 while the tucker bladeroll 86 tucks in one bag handle per revolution. For driving the handlefeeding and severing rolls, gear SSG meshes with idler 166 which mesheswith gear 44G of roll 44. In turn gear 44G coacts with gear 43G. Gear44G through idler 167 drives gear 42G, the latter meshing in turn with40G of cutting roll 40. Intermeshing gears 33G, 34G are driven by theintermeshing of gear 40G with idlers 168 engaging a gear mounted on thesame shaft as above mentioned gear 34G (the fact that the handlematerial must be initially fed at a speed twice that of the completedhandle has already been referred to).

The top sheet feeding mechanism is likewise driven by gear 77G whichengages idler 169 driving gear 75G. Idler 75G in turn engages 74G. Gear169 also engages 73G and in turn drives 72G of cutting roll 72. Feedrolls 70, 71 are driven from 72G through gear train 172, 175, 176 and70G as will be evident from Fig. 4. On the shaft carrying gear 176 ismounted gear 177 for printer 69 which receives its ink from inkpot 180by means of ink applicators 181, 182.

The drive for the conveyor mechanism for delivering completed bags fromthe machine comprises gear G which engages the main drum gear 77G in aclockwise direction, the drum of which is provided with groove 183 toreceive conveyor belts which cooperate with the above mentioned conveyorbelts which are driven from the machine by mechanism not shown.

It will be seen that the many advantages stated for our improved methodand machine have been realized in the preferred embodiment abovedescribed. Among the more important of these is the saving of paper orother bag making materials with the production of a bag of enhancedneatness due to its even top edges.

While We have devised a machine of which the bottoming mechanism is anintegral part, we wish it to be understood that if desired the bottomingoperation may be performed in other ways or in a separate device. Wewish it further understood that various changes may be made in ourmethod and machine without departing from the spirit of our invention orthe scope of the appended claims.
